In the icy waters of the Southern Ocean, whales and other marine mammals rely on krill to survive. But as the market for human dietary supplements and animal feeds booms, and climate change reduces krill populations, scientists worry there may not be enough to go around.

Supertrawlers Are Taking Antarctic Krill That Whales Depend On - Yale E360
Abatify Summary
Nature & Climate Perspective
**The industrial over-harvesting of Antarctic krill by supertrawlers threatens to destabilize the Southern Ocean's biological carbon pump, directly undermining critical marine biodiversity and natural carbon sequestration pathways. **
- Depleting krill populations disrupts the trophic cascade, starving whale populations that act as key biological engines for iron fertilization and ocean carbon cycling.
- Krill play a vital role in the biological carbon pump by transporting carbon to the deep ocean through fecal pellets and vertical migration, a mechanism threatened by industrial extraction.
- The cumulative impact of warming waters and intensive fishing compromises the long-term environmental stability of Antarctic marine sanctuaries, reducing their resilience as global climate buffers.
Market & Policy Outlook
**This ecological crisis highlights critical governance gaps in marine protection, challenging ICVCM Core Carbon Principles (CCPs) on environmental safeguards and raising Scope 3 risks for global supply chains. **
- The conflict between commercial krill harvesting and ecological preservation exposes the need for robust environmental safeguards under the ICVCM CCPs to ensure Blue Carbon initiatives are not compromised by external extractive activities.
- Corporations sourcing marine ingredients face escalating Scope 3 supply chain risks and reputational exposure as SBTi and biodiversity frameworks demand stricter accounting of ocean-impact metrics.
- Underdeveloped regulatory frameworks for international waters impede the integration of marine conservation into Article 6.2 or Article 6.4 mechanisms, limiting the financial liquidity directed toward Southern Ocean preservation.
